If you can't modify the layout.css.devPixelsPerPx pref on the about:config page, then you can edit the prefs.js file in the Firefox profile folder or temporarily create a user.js file that sets the pref.

  • user_pref("layout.css.devPixelsPerPx", "1.0");

You can use this button to go to the current Firefox profile folder:

  • ~/Library/Application Support/Firefox/Profiles/<profile>/

In Mac OS X v10.7 and later, the ~/Library folder is a hidden folder.
